PATENT OFFICE ASSIGNOR-TO THE- MONARCH MARKING OHIO, A CORPORATION OF OHIO TYPE CHASE Application led July 14,

This invention relates to improvements in type chase or holder for use in a machine of a character of price tag marking machines in which the user makes or changes thetype printing set-up as the priceV or marking Vdata to be printed upon pricetags. The chase is arranged to be readily slipped into or outof place in the machine and type bars each individually sustained inthe holder so that a printing set-up can be convenientlyk and quickly made or changed by the operator of the machine.

Theholder is preferably provided with several parallel slots for several rows or lines of type, with a wall of each slot provided with a series or plurality of parallel longitudinal grooves, each groove serving toguidingly receive longitudinal iins ex- Y Ytending from the type bars individually loeating and sustaining` the type side by side or, in spaced relation in a type receiving slot of the holder.

The present invention is primarily di-V rected to the structure of the grooved wall of the type receiving slots which wall may also constitute a division wall for several slots. Therefore, the object oi the invention is to forni a type bar sustaining wall of a holder of a sheet metal plate having its opposite ends morticed within the body of the holder facilitating the manufacture of the holder and providing a wall of greater stability and durability.

more fully set forth in a description of the accompanying drawings, in which:

Figure 1 is a front elevation of the improved type holder shown removably mounted within a printing head of a tag marking machine with the head depressed, bringing the type for a printing impression upon a- Further objects and advantages willpbeV 193e. seria1No.'467,s3s.

ydisplacement in the holder and imparts thel printingpressure directly to or upon the type bars which are suiiiciently loose in the holder to relieve the holder of any printing impres-v sion impacts. i

The upper ends of the type bars each, when makingV an impression, abuttingly bear against a Yplane under yface of the printing head'. The type bars are sustained in the holder by a shouldered engagement of a rib or iin extending longitudinally from one side.

of the type, and theend o'f a groove in a wall of the type receiving slot of the holder.

The holder possesses the general character-- istics of the holders now commercially used, in which the type bars are easily slipped out and into the holder formaking orv changing a printingy set-up.

The type bars are selectively and definitely set into and projected into rectangular slots in the holder with awallof each 4slot provided with series of grooves extending from -one end-for a portion of the depth of the wall. The grooves are uniformly spaced, the spacing governed by the size of the type so as to adapt the type to be set side by side approximately in Contact with eachk other. The longitudinal rib or lin on one side of the bar adapts the bar to be guidingly engaged into a selected groeve in the holder type receiving slots for making the printing set-up. This interlocking connection sustains the type bars against lateral displacement, and supports the bars within the holder. The type receiving slots are usually arranged inl parallelism andas close together as possible to make a. compactV several line set-up'capable of printing at least a four line .set-upupon' small sized tags, as for instance, Jewelryta-gs with a very small sized point of type.

The division walls for the slots, therefore, are required to be exceedingly thin. It is desirable to die cast the holder, which meth-` od, however, has not kbeen very practical on flo account of the extreme thinness of vthe grooved partition walls forming the type receiving slots, as the metal alloy used in die casting will not provide a partition wall of suliicient stability.

With the present invention the partition walls represent grooved steel plates morticed into the die casting or body of the holder.

Referring to the drawings, 1 indicates the forward end' ofv a printing head of a type marking machine in which the type holder or chase 2 is removably mounted. The head is reciprocated or swung 'toward and from` an impression platen 3, represented as an elastic pad recessed into' thev surface'of the table of the' machine overY which the to be price marlredY are successively advanced or moved to bring the tagsappropriately beneath'v printing head. The lower side of the head is channeled to receive the holder, withgthe inside face of the side walls l-Ll, which form the channel, longitudinal grooves or s :de ways 5, respectively I"receiving the 6 6 extending from the opposite/sides of the body portion of the holder 2.

The type holder 2 constitutes a rectangular casing lstructure provided with a. plurality of parallel type bar receiving slots therethrough in which the partition walls formthe'slots arcisteel Vplate inserts or partitions 7, each morticed into grooves formed in the body of the holder'Q.

Y A-liange- 8 entends from the forward' side of the body of the holder continuous 'with theflangfes 6r-6 of the sidewalls and terminates' with a finger holdv9. vThe holder supportingfflanges 6-7-6 which slide into the gi'iide ways of the printing. head are rela- Y tivelyof different lengths, one extending for the' fiilhlengt-h' of the body of the holder while the other for only a slight portion thereof. V This facilitates in making).- entry with the' slide ways 'and allows vthe holder to be.y slightly tilted to `clear the upper ends of the type bar, projecting through and beyond the upper face of the hold-er, from the base surface of the channel in the printing head with' which the butt end of the type bars engan-'e when making an impression.

The. opposite front and rear walls of the casing' have a plurality of aligned grooves 10 therein for the full height measurement of the walls, into which the steel parti Lon plates or` inserts 7 are' morticed', thereby providing, a plurality of type receiving slots Yl1.. Y Y

Each partition plate in one face side has a seriesvof' parallel grooves lQ'milled therein extending from one edge longitudinally of the plate partially across the face. thereof with-the terminal of each groove providing ashoulder or stop for the lin or rib of a type bar when slidablyengaged into the groove. The linindependently supports its type bar h provided with,

within the holder without disturbing the type bar set next adjacent thereto, and also permits the type bars to be selectively spaced from one another within a slot. The spacing of the grooves l2 is preferably governed by the cross-*sectional measurement of the type bars.

The partition plates are made of steel material of a very thin gauge and the grooves for the fins of the tv e bars accuratclv ma chined' therein, beforethe glateis inserted in the body of the holder.

'To-securely hold the partition plates or wall inserts rigidly in position the opposite vertical edoes ofthe plates are upset at several points as Vindicate-dat ill-14,the upsetting formingA burrs or protuberances which bite into the metal of the holder when the -plates are drivenV intothe 'morticing grooves of the holder. The body Vof the holder being a die casting has the grooves for morticing the partition or insert platesl cas-t therein. To allow the casting to'be withdrawn` from `the mold or die it is necessary that the side walls of the grooves be slightly inclined or tapered to give the necessary draft. Likewise, at the one or lower end of the grooves, the vwalls flare slightly outwardly due to the lilleting or roundingoil of the corners ofthe moldr or die.

The upper end of the groove, therefore, can be made extremely narrow to corres-pond to the small gage ofthe plate insert. By

upsetting theopposite longitudinal edges of' the plate at several points, preferably in the lower half of the plate, vwith the upsettingA at the several points on each edge 4in relative varying degrees corresponding to the degree of taper or draft allowed for the grooves, the plates can be inserted into the grooves, under a drive lit in absolute perpendicular plane. As the wall surfaces of theplatcs or inserts are absolutely plane the type very This snugly lit in the slots in the holder. materially improves `the structure of the io-lder and results in obtaining` a` higher quality printing without loclnngfor clamping steel yplate insert serves as a liner bearingdirectly aga-inst a wall of theholder.

Having described my invention, I claim: l. A type chase, comprising, a casing havinfr an opening therethrough, sheet metal plates'morticed into opposite walls of said casingin definite' spacedy relation dividing the opening into a plurality of type-receiving slots, the edges of the plates upset'at opposite sides provided With llanges for slidably engaging Within slide Ways of a printing head, said flanges being of dierent length. to adapt one ange to be engaged with its guide way in advance of the other.

In Witness whereof, I hereunto subscribe my name.
